FLANGE-OILER.

Specification of Letters Patent. Patentempe lfi 1914 Application filed September 18, 1913. Serial No. 790,47t.

To allwhom, it ma concern Be it known t atwe, ZAGHRIAH TIsHER- and (DHARLss T. Lrrorrrinno, citizens. ofthe- United States, residing at Spokane, in the county of: Spokane and State ot- Washing ton, have invented a new and useful Improvement in I langeOilers, of which the following is a specification.

This invention relates to improvements in wheel flange oilers or lubricators of thatclass wherein a ressure fiuid is employed for feeding the ubricant.

It is one of the objects of this invention to eliminate waste of" the lubricant by returning the same to the source of supply after the feed-' of lubricant has been shut oil so as to avoid the loss of lubricant which has been released from the shut-oil,

and which has not yet reached the wheel' flange.

A further object is to provide animproved form of oil applying wheel, adapted for engagement with the wheelflange, by reducing the surface of the oil applying wheel to approximately the area of its contact withpressure alone.

A further object is to provide a feedreservoir connected with the supply reservoir, so as to maintain a supply or levelof oil in the latter for feeding action by the pressure fluid, the feed reservoir being merely under atmospheric pressure and not being subject to any pressure from the-supply cylinder.

A further object is to provide an improved form of feeder for the oil applying means, whereby the oil fed will be localized when discharged on that portion of the oil applying wheel, which comes in contact with the wheel flange.

Other objects and features of theinvention will be more fully described in connectidn with the accompanying drawings, and will be more particularly pointed out in and by the appended claims.

In the drawings :Figure 1 is a view partly in section and partly in elevation of same in one position of adjustment.

Fig. 10 is a sectional view. of; an oil; supply valve con+- trolling plunger, detachedyfrom its associate parts. Fig. 11 is a sectionalview of an oil supply conduit: valve-spindle, detached from its associate parts. Fig. 12 is a sectional view of an air controlling valve, showing the Fig. 13 is a similar view, showing the valve in another position of adjustment.

Like characters of reference designate similar parts throughout the different figures of the drawings.

As illustrated, 1 designates the body of a railway vehicle and 2 the truck thereof, the latter being illustrated in supported relation with one of thetruck flanged wheels 3." An

air supply tank 4- is'indicated in a position below the car body and is provided with a supply pipe 5, which delivers to an air controlling valve 6. The air controlling valve 6 is connected with a pipe 7 which exhausts to atmosphere and is also connected with a supply pipe or oil feed or supply reservoir 8. A controlling handle 9 is provided for operation of a valve closure 10. The valve 6 is a three-way valve and when the closure 10 is in the position shown in Fig. 12, eX- haust is effected from the supply reservoir 8 direct to atmosphere through pipe 7, as indicated by the arrows. in the position shown in Fig. 13, communication is established between supply pipe 5 and supply reservoir 8 and exhaust through 7 is cut off.

to reservoir 8. Thus when the oil in supply When the valve isreservoir 8 is not under pressure, the level of its contents will be fed to a level equaling that of the feed reservoir 12, so that a supply will always be aflorded in the reser-- voir 8. A valve 14 is preferably disposed in reservoir 12 and forms the inlet to pipe 11' and is provided with a controlling stem and handle 15. By means of the valve 14, the supplyor feed may at any time be cut oif to reservoir 8. I

In-the preferred embodiment of our-invention, oil under air pressure is utilized to advance the oilsupply device for applying oil to the flange wheel into an operative position. In an alternative embodiment of our invention, air alone is utilized to-ad-j vance said devic'e'into an operative position and the 'oil is supplied under air pressure.

Referring to Figs. 7,. 8 and 9, 16 designates abracket'or support, which is adapted to be fixed to the truck 2. -A valve or plun' ger 17 is fixed in bracket-16 and is provided with an annularly grooved" nipple 13 to which a flexible connection 19' is attached,

said connection19-being secured to a pipe 20..communicating with the supply pipe or reservoir -.8. The plunger 17 .is provided -with a' bore 21 e'xtendin throughout its length to'its'discharge en 22.- The plunger -17 .is provided; with a luralityf of an-j nular grooves 23 toz-p'rovi e.;oil receiving cavities to. lubricate the periphery f of the plunger, :In two of therendxgroo'ves 24 :We may prov de suitable packing.- to *prevent by- A, eylind. the plunger 17, and isprovided with-a head 26 against which oiland air, or more properly2 speaking the oil under air pressure engages to advance the cylinder 25.110 an o eratiive or oil applying position. A suitable packing 27-.may serve as an abutment to neutralize shock resulting from return impact :of the cylinderhead with the end of the plunger. 7 ;Return movement of the cylinder is effected byrmeans which may comprise. springs 28,- adapted for connection withthecylinder head at 29, and with the bracket -16 at- 30.

Advancing movement of the cylinder 25 under oil pressure through the bore 21 will 0 en a ort 31 to admission of oil supply in t e3 cy11nder between the head 26 and the end of the, plunger 22. Port- 31 delivers to a milled ofl or recessed portion 32 of a valveconduit spindle 33, which is disposed at right angles to the lunger 17. The" spindle '33 isprovided wit a. port 34, which leads from thefmilled ofi recess 32 to a bore or conduit 35,- having-feed member discharge ports 36 and 37. The end of the bore 35 may, be closed by any.v suitable form; of plug.

. 38.,3The 'spindle33 is mounted-in the cylinder: structure 25 and. stufiing boresor,

packing glands 39 serve to prevent egress r is slidablyiimounted upon of oil lengthwise and exteriorly of the spindle 33 and also to permit of longitudinal movement of said' spindle. One endofthe spindle 33 is reduced to form a shoulder40,

and on the reduced end of said spindle we mount oil feeders 41 and 42. Said feeders so as to be nonrotatively secured to the spindle 33. The spacing element 44 is interposed between said feeders to hold the same in proper spaced relation. Feeder. 41 is with the elongated discharge port 36, and likewise, feeder 42is provided with .a port 46, which registers with elongated discharge port 37. The ports 36 and 37 are sufiiciently long to aflord registry with'the ports 45 and 46 irrespective .of relatively limited adjustments totake upwear.

Means is provided for preventlng rotation 'are'jammed against shoulder 40 by a nut 43,

provided with a port 45, which registers v of the feeders 41 and42 and the spindle 33 and permitting :longitudinal shifting move-' to the or wheels 50 ,and 51- [engage the feeders 41 and 42 in a manner ion supply, throughout the facial areaof each a disk and thereby effect a very material economy. .v t

The oil applying disks50 and 51 are shown threaded upon a sleeve 56, which is slidable upon a stud 57, mounted in the. cylinder structure 25. When the disks are.

in place, they are locked ,by jam nuts 58 and 59.- Springs 60 and 61 yieldingly resist movement ofthe sleeve .56 in opposite directions from the position, shown, and

spring 6O abuts against structure 25 while spring 61 abuts againsta The disks 50 and 51jaresuitably flared so as to insure engagement with the flange of wheel 3 and in view of the fact that the bracket 16 is mounted on the truck 2, it

will be seen that said disks will always be;

in approximately alined relation with the wheel flan e. However, any slight la k of registry will be accommodated by the sliding movement afforded the sleeve 56'and the flared disks .will serve to grasp opposite faces-of the wheel flange and position them selves in accordance with any lateral plays-f movement of the truck wheel .withrespect.

to'the truck both on straight and curved lines as track. Asthe oil.applying.,-disks;

are'pshifted by relative play of the truck wheel, they will likewise'shift the feeders i1 and 42 and the spindle 33, and the latter will always be in communication with port. 31 by reason of the elongated recess 32, so that in all positions which the spindle 33' may assume a supply of oil will be eflected.

The port 31 is L-shaped and at its lower portion we provide means for controlling the flow of oil, which may be inthe form of a needle valve 63 which enters the port from a lateral position, as clearly shown in Fig. 9.

It will now readily be seen that when air pressure is shut oil through valve 6, the springs 28 will instantly return the cylinder structure 25 to the position shown in Fig. 8, thereby cutting ofi port 31 and causing return of the major portion of the oil supply, back to the supply reservoir 8, thereby avoiding waste. Such quantity of oil as may be retained in the spindle 33 will be negligible and will not flow out of the spindle by reason of the'lack of an air vent. Immediately upon release of pressure of air on the instead of under the oil fed pressure, we may provide the guide 6-1 with a bore 66 opening to the cylinder head 26, a suitable packing 67 being interposed for a purpose similar to packing 27. The guide 64 is provided with a nipple 68, adapted for attachment to a flexible connection 69 communicating with a pipe 70. Pipe 70 is directly connected with valve 6 so that air under pressure will force the cylinder structure forwardly. Supply reservoir 8 will be connected to pipe 70 so that suflicient air pressure will be available to impart a force feed to the oil simultaneously with pressure advancement of the cylinder structure.

While we have described the form shown in Fig. 8 as a modification of the preferred form, still, it will be seen that where it is desired to merely utilize the valve-like plunger 17 for oil feed under pressure to advance the device to an oil applying position, the plunger 64 may simply serve as a guide and, therefore, it will be seen that We have embodied in this one structure two forms of our invention, and in either utility all of the parts will coact and function and no part will remain idle, although in the first-named form the plunger 62L will not function in its most complete capacity It is believed that the advantages and utility of our invention will be fully understood from the foregoing description, and

while we have herein shown and. described specific forms of our invention, we do not wish to be limited thereto except for such limitations asthe claims may import.
